BOLTlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 461,843, dated Qctober27, 1891.

Application filed June 1, 1891- Serial No. 394,724. (No model.)

T0 at whom, it may concern:

Be it known that I, SYLVANUS A. NoEDYKn, of .Kansas City, Wyandottecounty, Kansas, have invented certain new and useful Improvements inBolting-Machines, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, forming apart hereof.

My invention relates to machines for separating different sizes ofparticles of various ground grains, such as wheat, corn, oats, rye,barley, buckwheat, &c.; also, for removing foreign substances therefrom,such as sticks, straw, dirt, cheat, and other impurities; and the objectof my invention is to produce a simple, durable, and comparativelyinexpensive form of bolting-machine which shall be rapid and effectivein its operation, and which shall also operate without Waste of materlaland automatically clean or clear its screens or meshes during theoperation of the machine.

To the above purposes my invention consists in certain peculiar andnovel features of construction and arrangement, as hereinafter describedand claimed.

In order that my invention may be fully understood, I will proceed todescribe it with reference to the accompanying drawings, i which- Figure1 is a central vertical longitudinal section of my improvedbolting-machine on the line 1 1 of Fig. 4. Fig. 2 is a transversevertical section of the same 011 the line 2 3 of Fig. 4, thebolting-screens being shown in lowered position. Fig. 3 is a similarsectional View on said line 2 3, showing the sieves in raised position.Fig. 4 is a horizontal crosssection of the machine on the line 4 4 ofFig. 2. Fig. 5 is a perspective View of the screens and adjacentoperative parts of the machineframe, a portion of the sifting-screenbeing broken away and removed to more clearly show the construction ofthe screens. Fig. 6 is a horizontal cross-section of the same on theline 6 6 of Fig. 3. Fig. 7 is a transverse vertical section of themachine on the line -7 7 of Fig. 3, the parts being shown on an enlargedscale. :Fig. 8 is a detached perspective view of oneof the movabledeflectors for preventing mixture of useful material with wastematerial. Fig. 9 comprises detached perspective views of theratchet-disk and the plain disk, and also of the rods actuated thereby.

In the said drawings, 1 designates the framework or casing of themachine, said framework or casing being preferably of oblong rectangularform, and? designatesa feedinghopper, which is preferably located at oneend of the machine, adjacent to the higher end of the inclined screens,to be hereinafter described. WVithin this casing 1 is placed ahorizontal partition 3, which divides the casing into an upper and alower compartment, as shown, while at the opposite end of the casingfrom that to which the hopper 2 is attached is placed a discharge-spout4, protruding from the lower part of the casing. In the lowercompartment of this casing are located two longitudinally-extendingscreen-frames, which are inclined downwardly from those ends to thehopper end of the casing or to those ends which are adjacent to thespout end of said casing. Each of these screen-frames consists of twoparallel side pieces 5, connected together at their ends which areadjacent by two transverse end pieces 6. At the ends of their outersides these screen-frames are provided with outwardly-extending metalbrackets 7, to the outer ends of which are pivotally connected the lowerends of vertical links 8. The upper ends of these links are pivotallyconnected to the inner ends of L-sh aped brackets 9, which are securedto the inner surfaces of the sides of the casing 1 at the endsthereof.The pivots which connect the outer ends of the brackets 7 to the lowerends of the links 8 also pass through elongated slots in theinwardly-extending arms of L-shaped brackets 10. Said brackets extendhorizontally inward from. the inner surfaces of the sides of the casingat the ends thereof and serve to prevent any longitudinal vibrations ofthe screenframes. At the ends of their inner or adjacent sides thesescreen-frames are provided with inwardly extending metal arms 11,through the inner overlapping ends of which pass bolts 12, which alsopass through the lower ends of links.13. The upper end of each of theselinks is connected to the lower end of a vertical rod 14, to behereinafter more fully described. To the upper surfaces of the sidepieces of the screen-frames are secured meshings 16 of open orforaminous fabric, woven wire, perforated metal, or other similarforaminous material of finer or coarser mesh, according to the characterand condition of the grain to be operated upon, and to the upper sidesof the outer side pieces of said screen-frames are secured strips 17 ofheavy fabric-such as canvas or other flexible and at the same timeimpervious materialthe outer edges of said'strips being securelyattached to the inner surfaces of the sides of the casing 1, and thusclosing the spaces between theouter sides of the screens and the innersurfaces of the sides of the easing, so that no material can dropthrough at these points. Upon the upper sides of the cross-pieces 6 atthe higher ends of the screens are secured Vertical guards 18, the innerends of said guards being slotted to receive a rivet or bolt 19, and thesaid guards serving to prevent any incoming grain from the hopper 2 fromescaping over the higher ends of the screens. I

It is to be observed that the inner end of the discharge-spout 4 of themachine projects inwardly beneath the lower ends of the screens, so thatno waste shall occur as the bolted grain passes out of the machine fromthe screens.

Immediately beneath the meshing or perforated material 16 of eachscreen-frame and resting upon cross-bars 19 of said screenframes are anumber of longitudinal bars 20, to the upper sides of which are 'secureda suitable number of transverse scrapers or clearers 21, which lie indirect contact with the under sides or surfaces of the meshings orperforated portions 16, and which by longitudinally-reciprocatingmovements serve to keep the meshes or perforations open and free fromaccumulated impurities. These reciprocating movements of the scrapersare produced by vertical rigid cams or inclines 22, which are secured tothe inner surfaces of the opposite ends of the casing, the workingsurfaces of the inclines at one end of the machine extending downwardand inward and those of the other set upward and inward. The workingsurfaces of these inclines or cams are engaged bythe protruding ends ofcertain of the longitudinal pieces 20, and the arrangement is such thatas the screens rise and fall, as hereinafter described, the inclinesshall force the scrapers longitudinally of the screens, first in one andthen in the opposite direction longitudinally.

The flooring 23 of the machine inclines downwardly and inwardly from thesides toward the middle of the machine, and at the middle is formedalongitudinal compartment, which is located in the bottom of the casing 1beneath said flooring, and which is divided into two parts by a verticallongitudinal partition 24. In each of these compartments is located aspiral conveyer 25, the shafts of which are provided at one end of thecasing with intermeshing gear-wheels 26, and one of which shafts isprovided at the opposite end of the machine with a pulley 26, to whichpower is applied through a suitable drivingbelt. Immediately above thepartition 24 is mounted a horizontal longitudinal rod 28, to which arepivot-ally suspended a number of deflectors 29, each of said deflectorsbeing of substantially U form,having triangular sides, through theapexes of which the rod 28 passes loosely. The scrapers 21 carry off thedirt and other finer impurities from the screens, and such impuritiesfall upon the floor 23, from whence they enter one or another of thecompartments containing the conveyers, according as the deflectors 29are set. If a break or a weakspot should occur in any part of eitherscreen, the deflector immediately beneath such break or weak spot is setoppositely frointhe others, and the escaping useful material will becarried to the opposite conveyer and discharged from the machine forrescreening or rebolting. In orderto afford access to these deflectors,doors 30 are hinged at one side of the conveyer-compartments, and accessto the doors is had through a suitable opening in the lower part of thecorresponding side of the casing.

In the upper part of the machine-casing is mounted a horizontallongitudinal revoluble shaft 31, which carries at one end a pulley 31 towhich power is applied through a suitable driving-belt. Upon each end ofthis shaft, just within the casing 1, is rigidly secured a ratchet-disk32, and closely adjacent thereto a disk 33, having a plain periphery.These two disks at each end of the shaft are set eccentrically upon theshaft and at the same side thereof, as shown. The rods 14 above referredto are bent laterally at their upper ends to pass by the shaft 31, andattheir upper ends these rods pass through the top of the casing 1. Eachof these rods 14 carries a pin or stud 34, which engages the surfaces ofthe teeth of ratchet-disk 32, the direction of rotation of the shaftbeing such that the pin or stud travels from the inner to the outer endof one tooth and then drops downward upon the inner part of the nexttooth. It will thus be seen that as the shaft 31 rotates the eccentricratchet-disks gradually elevate and depress the rods 14, and that theteeth of the ratchet-disks cause said rods to intermittingly dropslightly downward while the rods are rising. Corresponding rising andfalling and vertically-vibrating movements of the screens are thereforeproduced, so that the material on said screens is thoroughly agitatedand also kept ina jolted condition while passing over the screens. Eachrod 14 carries two adjustable stops 35, between which is interposeda'coiled spring 36, which surrounds the rod. Between the upper end ofeach of these springs and the under side of the corresponding upper stop35 is interposed the lower end 37 of a second surround the rod 14. Thisrod 38 is bent laterally at its upper portion to clear the shaft 31 andat its upper extremity passes through th e top of the casing 1. Two pinsor studs 39 project laterally from the rod 38, so as to come intocontact with the upper and lower surfaces of the plain periphery of thecorresponding eccentric disk 33. Thus as the shaft 31 rotates the rods38 steadily rise, the upper ends of the springs 36 being pressedintermittently against the lower ends 37 of the rods 38 and then allowedto expand. This expanding action of the springs 36 assists theintermittent depressions of the screens by gravity, and thus hastenssuch intermittent depressions, so as to impart sharp jolting movementsto the screens, by means of which the grain is tossed and thoroughlyagitated and its impurities are effectively separated from the mass ofthe grain.

From the above description it will be seen that I have produced asimple, durable, and inexpensive machine which operates with greatrapidity and which is adapted to economically bolt or grade a greatvariety of grain. It is also to be observed that this machine is adaptedfor use as a scalper to be used on brake-rolls.

Having thus described my invention, what I claim as new therein, anddesire to secure by Letters Patent, is

1. An improved bolting-machine comprising a pair of vertically-movablescreens pivoted together at their adjacent edges, and a rod connected tothe pivotal end of the screens and engaging an eccentric revolubleratchetwheel, substantially as set forth.

2.
